Jiafeng coal (Jincheng, Qinshui coalfield)
Shanxi, Qinshui coalfield (Shanxi Formation), China
Othercharbon (Hg)
- Type
- Coal deposit (subbituminous C coal to subbituminous B coal, Permian)
Subbituminous C coal to subbituminous B coal seam of Permian age, calorific content of 9,500 Btu; mercury with a mean δ202Hg of -2.32 ‰ and Δ201Hg of +0.29 ‰ (Biswas et al., 2008). Sample homogenised at the University of Michigan; with HE-1, signature judged distinct enough to be possibly globally unique. Indicative coordinates (Jincheng city).
